Internet radio offers a lot of great music and programming for free, but not all of it can be downloaded whenever you're ready to listen. Lifehacker reader Luke points us to a quick tutorial on setting up your Linux system to record radio or music while you're away using the free kcron, Mplayer, and Lame tools. It's a fairly simple guide that leaves you with an MP3 of the program you were trying to catch. Windows recording enthusiasts can check out a similar guide for Windows Luke pointed us to, which requires a bit more command line work and tinkering. Thanks Luke!
